We are happy to inform you that a new production batch of FreeIMU v0.4r3, featuring the MPU6050 accelerometer and gyroscope, the HMC5883L magnetometer and the MS5611-01BA03 pressure meter altimeter module (now in metal shielding case!), is available for sale online.

Dear friends, it's been three months since the death of Fabio, and until now we had to make sure on the way in which we want to keep his work alive.

We're his friends at FabLab Torino and Officine Arduino, with us are his girlfriend, his family, and the guys who flew with FreeIMU.

Before setting out the news about Fabio’s website and the continuation of his work, the family would like you to know that most of the organs donated by Fabio at the time of death have given a second chance to many people. And this is already good news.

I'm happy to finally publish the code for drawing nice 3D scatter plots of the incoming accelerometer and magnetometer data for the Ellipsoid into Sphere calibration available in the FreeIMU GUI. This will be soon released in upcoming v0.3 of the FreeIMU GUI but for now is available only on the repository.

This will allow users to have a direct realtime feedback on the performed motions and how good/wrong their sensors are calibrated.

Below a couple of screenshots. Note how screwed up was this magnetometer on it's Z axis, compared to the calibrated sphere output.

I'm happy to inform you that I've finally created a community website for the FreeIMU project. You can see it at freeimu.varesano.net.

Right now, it's a simple forum website built on top of Drupal with still a pretty crude graphic.. I decided to use Drupal instead of other forum specific platforms (SMF, phpBB, vBulletin, etc..) because ideally this website will evolve to the main source of information for the FreeIMU project thus a simple forum wouldn't have been enough.

In the future, I'll be slowly moving the content of the FreeIMU webpage there and possibly extend it. I'll also add other features like wiki, documentation pages, etc..

So, if you are using FreeIMU and you wanna join the discussion, please join me and register at freeimu.varesano.net!
